EDITORS DAILY CRIMSON. - Again the injustice of the present marking system has been shown in a conspicuous manner. Natural History 5 is by no means a "snap course." It requires at least six hours a week laboratory work, besides a knowledge of the points taken up in the lectures. The majority of the members of the elective have done faithful and careful work in the course, yet the highest mark for the half-years work was 88, while a large number ranged between 65 and 75. When this is compared with a soft course like the Mineralogical half of Natural History 4, where a man does nothing until a few hours before the examination, and easily attains a mark of 90 to 100, it will readily be seen that under the present system, marks are very poor indices of industry or ability.
